Issue with Decimal Points in Currency Conversion for Apple Pay Transactions

Hello,

Currently, I’m facing an issue that I cannot understand. I’m trying to add three currencies to my e-shop: https://nsm-store.com. These are: Omani Rial, Kuwaiti Dinar, and Bahraini Dinar. The converter itself and prices on the product page, cart, etc., are displaying correctly. However, when, for example, the displayed total price is 19.87 Omani Rial and the customer wants to pay via Apple Pay, the total amount changes from 19.87 Omani Rial to 1.987 Omani Rial. It kind of removes one decimal always. The same applies also to the above-mentioned currencies.

See piectures below as an example!

Can you please help with this?

Thanks,
Muaadh
